Technical Specifications

Screen mesh, contact material, inlet, discharge outlets, sealing, and screen-cleaning arrangements can be configured according to the application.

The capacities above are reference values for standard configurations. Actual throughput depends on material density, moisture, particle size, flowability, mesh opening, feed rate, and separation requirements.

Working Principle

A vertical vibration motor with eccentric weights generates the centrifugal force that drives the screening assembly.

The resulting vibration produces horizontal, vertical, and inclined movement. Material entering the screen spreads across the mesh as it moves toward the discharge outlet.

Particles smaller than the selected aperture pass through the mesh, while oversized particles remain above the screen and are discharged separately.

For multi-deck screening, different mesh sizes can be installed to separate several particle-size fractions in one operation. Similar industrial vibro sifter designs use eccentric weights to create the multi-directional movement required for material separation.

Key Configurations

1–5 Decks

A single deck is suitable for one screening cut. Multiple decks can separate several particle-size fractions in one operation.

Screen Mesh

Mesh size is selected according to the required separation size and material characteristics. Fine powders may require suitable screen-cleaning arrangements to reduce mesh blinding.

Construction

Carbon steel is suitable for many general industrial applications. SUS304 or SUS316L can be selected for applications requiring corrosion resistance, hygiene, or specific product-contact requirements.

Continuous Screening

Material can be continuously fed and separated, with different fractions discharged through corresponding outlets.

These configuration choices are consistent with the main specification categories used across current vibro sifter product pages, including screen diameter, deck number, mesh, capacity, motor power, and construction.

Screening Applications and Examples

The machine can be used for screening powders and granules in food, pharmaceutical, chemical, mineral, ceramic, and other industrial processing applications.

Typical materials include flour, sugar, salt, starch, spices, pharmaceutical powders, pigments, mineral powders, ceramic materials, and metal powders.

The values above are application-specific references rather than standard machine ratings. Actual capacity varies with material properties, mesh size, moisture, feed rate, and required separation.

How to Select the Right Model？

Model selection should be based on the complete screening requirement:

The screen diameter is selected according to the required screening area and throughput. The number of decks depends on how many particle-size fractions need to be separated. Mesh size is determined by the target separation size and material characteristics.

Providing these parameters allows the appropriate configuration to be evaluated before quotation.

Frequently Asked Questions

What capacity can it handle?

Standard models provide reference capacities from approximately 100 to 2000 kg/h. Actual throughput depends on the material, mesh, feed rate, and screening conditions.

How many decks are available?

The standard range can be configured with 1–5 decks. A single deck is suitable for one screening cut, while multiple decks are used for multi-fraction separation.

Can the machine be customized?

Yes. Screen diameter, deck number, mesh, construction material, inlet, discharge outlets, sealing, and screen-cleaning arrangements can be configured according to the application.
